Hey Lew,
Those are great photos of Chilton Flats and of Tom Cave's telescope. With regard to the similarity of Mr. Cave's mount to a Schaefer design, I refer the reader to Larry Adkin's Tom Cave website at: http://www.cerritos.edu/ladkins/Cave/thomas_cave_observatory.htm
Larry also has recognized the possible connection with this early mount.

Also, the original post about the ebay Schaefer telescope indicated that the seller bought the scope at garage sale in West Covina. Maybe Mr. Ballas lived in West Covina or nearby.
